- Castlemap is a free interactive map of 2,435 castles, fortresses, and palaces across 129 countries.
- The map is built entirely from open data: Wikidata, Wikimedia Commons, Wikipedia, OpenFreeMap, and Natural Earth.
- It curates only verified landmarks with real photos, English Wikipedia articles, and exact coordinates, balancing countries for explorability.
- Users can add missing castles by improving their Wikidata entries (coordinates, photo, English article) for the next refresh.
- The full dataset is free to download as GeoJSON or CSV under CC0.
- France has the most castles (183), followed by Italy, Germany, England, and Japan.
- Each castle has a 'fame score' based on Wikipedia language editions; Versailles ranks #1.
- The atlas is curated, not exhaustive, focusing on significance over quantity.
